Renbei

A cup of divination. This kind of divination was introduced from the Han area and is popular in all parts of the Li nationality. Made of two pieces of wood or bamboo. The flat side is called "Yang" and the convex side is called "Yin". When one side is flat and the other side is convex, it is called "forgiveness" in Qiongzhong Li and Miao Autonomous County. In Dongfang and Ledong Li Autonomous County, it is called "Sheng". It's called "Da" in Sanya. It has a wide range of uses, such as ghost hunting, forbidden hunting, looking for a job, looking for a cow, hunting, taking possession, and recognizing someone (or "big tree" or "big stone") as an adoptive father. Usually thrown on the ground three times in a row. If there are three Yin San Yang and three wins (or "two yin and one win" and "two wins and one yin"), it is a bad omen. When there are only two yang and one yin, two yin and one yang (or "two yang and one win" and "two wins and one yang"), it is a good omen (in the East); It is a good omen to have three yang or win; One yin, one yang and one victory is great luck (Ledong area); Every three times, yin and yang appear, which is a good omen (Sanya area); Anyone who appears "forgive, forgive, forgive" or "yin, yin" or "yin, yang, forgive" three times is invited to the "ghost". If the order is wrong, it means that no ghosts have been invited (Qiongzhong area).
